The “1955 Chevy” in Two-Lane Blacktop was actually three 1955 Chevrolet 150 two-door sedans built by drag racer Richard Ruth’s Competition Engineering: two primary picture cars and a separate steel-bodied stunt car. Their engines and jobs differed. One of the primary cars was later transformed into Bob Falfa’s black Chevy in American Graffiti.
Why there was more than one “Two-Lane Blacktop” Chevy
Director Monte Hellman’s 1971 film follows the Driver and Mechanic as they race their ’55 Chevrolet against a Pontiac GTO across the country. The Library of Congress describes the journey as a race that gradually becomes a roadside odyssey, making the Chevy more than a prop: it is the pair’s home, workplace and instrument of escape. The film’s mood is captured in Hellman’s reflection: “I am romantic in the way the Camus is romantic,” he said. “I feel a nostalgia for what can never be.” Library of Congress essay on Two-Lane Blacktop.
Ruth built three cars for the production, based on his own big-block 1955 Chevy. Accounts sometimes call different vehicles simply “the car,” which is why engine descriptions can seem to conflict. The clearest way to distinguish them is by filming role and configuration:
| Production car | Role and construction | Reported original specifications |
|---|---|---|
| Exterior picture car | Used for exterior shots; fiberglass panels | 427 crate motor, M-22 Muncie transmission, 4.88 Oldsmobile rear, and straight axle |
| Interior camera car | Primary car used for interior camera work; fiberglass panels | 454 crate motor and similar core drag-car equipment; the surviving car is also described with an M22 four-speed |
| Stunt car | Separate all-steel vehicle | 454, TH400 automatic, and Oldsmobile rear with gearing not specified |
These are reported build configurations, not a claim that every component stayed unchanged throughout filming or the cars’ later lives. The distinction matters: a reference to a 427 can describe the exterior car, while a reference to a 454 can describe the interior car or the stunt car.

What made the cars look and work like gassers
Ruth built the cars for drag-racing use, giving them the high-nosed, stripped-down character associated with gassers. Depending on the individual car and its configuration, reported features include a custom straight axle, fiberglass front end and other body panels, sliding Plexiglas windows, a tunnel-ram intake and dual carburetors. The stunt car was the steel-bodied exception. Equipment varied by vehicle, and later movie work or restoration altered some details.
The production cars’ purpose was not to provide one definitive showroom-style specification for a 1955 Chevrolet. They were working film cars, built around practical needs such as camera placement, action work and performance. Accordingly, a detail attached to one car should not automatically be assigned to all three.

How one became Bob Falfa’s Chevy in American Graffiti
After Two-Lane Blacktop, one of its two primary cars was modified for American Graffiti. It was repainted black and changed for its new role, including alterations to the interior, windows, trunk, wheels and hood scoop. It became the car driven by Bob Falfa.
That history does not mean the car looked exactly the same in both films, nor that every Two-Lane Blacktop Chevy went on to appear in American Graffiti. Richard Ruth later examined detailed photographs and authenticated the black car as one of his original builds. The identification refers to one of the three cars, not to an unchanged vehicle or a universal specification for the film’s Chevy.

What happened to the surviving interior car
The interior camera car went to a studio mechanic after filming and later passed through other owners. It was located in Canada in 2000. Walt Bailey brought it back to the United States and worked with Ruth on a preservation and restoration project.
Sports Car Market records that the car sold at Barrett-Jackson Scottsdale on January 17, 2015, for $159,500 including buyer’s premium. That is a historical auction result, not a current appraisal or evidence of its present ownership or display location. Sports Car Market’s sale profile.

How to make sense of conflicting descriptions
When an account gives a different engine, body or movie history, first identify which vehicle and time period it means. These distinctions resolve many apparent contradictions:
- Filming role: exterior picture car, interior camera car, or steel stunt car.
- Time period: original Two-Lane Blacktop build, later American Graffiti conversion, or restored configuration.
- Mechanical details: the 427 exterior car is distinct from the 454 interior and stunt cars; the stunt car also had a TH400 automatic.
- Body construction: the primary cars used fiberglass panels, while the stunt vehicle was all steel.
- Later history: the Bob Falfa car and the surviving interior car have separate documented stories.
There is no single complete specification that accurately describes all three cars across both films and their later changes. Treating “the ’55” as one immutable vehicle erases the very differences that explain why the accounts vary.
